Replace or OS upgrade from 20.04 for Deploy VMs

Problem

Similar to our dev instance, our deploy instances are running Ubuntu 20.04 LTS which goes off support on 2025-05-31.

For Ubuntu 20.04 LTS, this support will last until 31 May 2025.

-- Ubuntu 20.04 LTS Standard Support is coming to an end. Here’s how to prepare.  | Ubuntu

Assumption to check - what activities do we do on the deploy nodes? If only migrations jobs, can we move the work to GKE?

Exit Criteria

1. Decide if we should move these nodes to K8s - probably move migrations to K8s jobs

Alternative plan:

2. Pick the LTS to which we should upgrade (24.04)
3. Make an upgrade plan and change issues.
4. Do the upgrades.
